Weapon upgrade paths

Weapon upgrade paths

Every run starts from one of six weapons, and each one grows into its own set of upgrades. Open a path to see which branches exist, what each upgrade changes and where a route ends.

Weapons outside the six starting paths

These weapons do not grow out of a starting weapon; they appear through their own drops, events or rewards. Some carry upgrades of their own, and any that a starting weapon path also reaches is marked.

How weapon upgrades work in a run

You begin a run with one of six weapons and can upgrade it twice. Each choice commits you to a branch, so the first upgrade already decides which final forms stay reachable. A few weapons are never part of these paths and only appear on their own.

How to use this page

Work outwards from the weapon you are holding:

  1. 1

    Open the path for your current weapon: each row runs from a first upgrade to the second upgrades it leads to.

  2. 2

    Select any weapon to see its official actions and verified values in the panel beside the path.

  3. 3

    Use the highlight buttons to spot the upgrades that add fire, ice or lightning damage, or that switch to ranged attacks.
